UASCALE= the anchor user-scale value of 1 logit = 0 |
Top Up Down
A A |
Specifies the number of units per logit of the anchor values.
UASCALE=0 - the anchor values are in the current output scale set with USCALE=
UASCALE= other value - this is the units per logit of the anchor values.
UIMEAN= and UPMEAN= are ignored when there are anchor values.
Example 1: The anchor values are user-scaled such that 1 logit is 45.5 units, so that differences of -100, -50, 0, +50, +100 correspond to success rates of 10%, 25%, 50%, 75%, 90%:
UASCALE = 45.5 |
; 1 logit = 45.4 user-units |
Example 2: The anchor values are on one scaling, but you want the reported values to be on another scaling.
UASCALE= 5 |
; there are 5 units per logit in the scaled values |
USCALE=10 |
; you want 10 units per logit on the reported values |
Example 3: The anchor measures are in logit scaling, the output measures are to be in user-scaling.
UASCALE= 1 |
; anchor values in logits |
USCALE=30 |
; 30 user-units per logit |
Example 4: Anchor measures are in same scaling as the output measures
UASCALE= 0 |
; anchor values in USCALE= scaling |
USCALE=user-value |
; also used for anchor values |
Example 5: Anchor values are scaled in Probits, not Logits
UASCALE = 0.588 |
